Razor



*una

Patented July I0, 1934 UNITED STATES 'PATENT OFFICE 6 Claims.

This invention relates to new and useful improvements in a razor.

The invention has for an object the construction of a razor which is characterized by the pro- .vision of a pair of movable members thereon, one

member inscribed with indicating marks indicating the edges of the razor blade and the other inscribed with consecutive members indicating the number of times any of said edges is used, and

a means for pointing out one inscription on each of said pair of members corresponding with the information desired.

It is a still further object of this invention to arrange said members rotative upon the handle of the razor.

Furthermore it is proposed to provide a sleeve constructed with a pair of windows, and to arrange said pair of members rotative in the ends of the sleeve in such a manner that the indication marks are selectively viewable through the windows.

Furthermore an arrangement is proposed whereby each of said members is resiliently held in said position so as not to accidently move therefrom.

Still further the invention proposes theconstruction of a handle for said razor arranged with a shoulder adapted to form an abutment for one of said pair of members, and threaded on its other end for receiving a nut adapted to form an abutment for the other of said pair of members arranged in such a manner that the nut holds the pair of members and an interposed sleeve in place upon the razor handle.

Still further it is proposed to construct a razor as described which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:-

Fig. 1 is a side elevational view of a razor -constructed according to this invention.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a plan view of the blade used in conjunction with the razor.

Fig. 4 is an enlarged sectional view taken on the line 4-4 of Fig. 1 and showing the handle only.

Fig. 5 is a side elevational view of one of the members with the indication marks.

Fig. 6 is a side elevational view of the other member with indication marks.

Fig. 7 is a perspective view of a spring used in 60 the device and adapted to resiliently hold the pair of members against accidental motion.

The razor according to this invention comprises a razor head consisting of a guard member 10 and. a blade support member 11 adapted 65 to engage on opposite sides of a razor blade 12.

A central stud 13 projects from the blade support 11 and is adapted to pass through an opening in the razor blade and in the guard member 10 and threadedly engages in the upper end 14 of a 70 handle 15. A pair of pegs 16 project from the blade member 10 for holding the parts together in proper relation. So far, the razor construction is according to conventional practice. The blade 12 is also of conventional design excepting that 75 its edges are indicated by some marks as for example A, B, C and D, as illustrated in Fig. 3.

The razor now departs from conventional construction in the provision of a reduced portion on the handle 15 forming a shoulder 16. A tube 80 17 is engaged over the reduced portion of the handle 15 and at the upper endis provided with a sleeve 18 and at the lower end with another sleeve 19, each sleeve having reduced portions 20 disposed within the tube 17 and enlarged nuts 85 21 extending over the edges of the tube and formed with knurling, clearly shown in Fig. 1 to facilitate manual turning. The inner diameters of the sleeves 18 and 19 are such that they rotatively engage upon the reduced portion of the handle 15. The tube 1'7 is formed with an upper window 21 and a lower window 22. The upper sleeve 18 has a plurality pf indication marks upon its reduced end, which is disposed within the tube 17, and these marks correspond with the indication marks upon the edges of the blade 12, as shown on the drawing comprising the letters A, B. C and D. These letters are so arranged that they are selectively viewable through the window 2'1, depending upon the position of 10 therotation of the sleeve.

The lower sleeve 19 is also provided with indication marks, preferably, consecutive numbers clearly shown in Fig. 6 to indicate the number of times each of the edges of theblade 12 is used. 105 These numbers are also selectively viewable through the windqw 22. A nut 23 threadedly engages at the lower end of the handle 15 and has a shoulder abuting against the bottom sleeve 19 so as to hold the sleeves 18 and 19, and 110 the tubular member 17 in place upon the handle.

A provision is made to hold the sleeves 18 and 19 against accidental turning. This provision comprises'a plurality of teeth 24 formed upon the inner ends of the sleeves 18 and 19 and adapted to be resiliently engaged by the pointed ends of a spring 25 riveted longitudinally upon the inside of the tubularv member 17 at its center.

The operation of the device may be understood by assuming a new blade just placed within the razor head. Attention is called that the razor guard 10 is so constructed as to necessitate use of one side only, see Fig. 2, so that only one edge of the blade may be used. Assume that the blade is placed into the razor head so that edge A is ready for use. Then the sleeve 18 is turned to a position in which the letter A is exposed from the window 21. Then for each subsequent shave the lower sleeve 19 is turned to indicate that the edge A has been used two, or three times, etc. After a certain number of shaves have been taken on one edge, a new edge is used and the sleeve 18 turned to indicate this new edge. The number of shaves taken on this new edge are also recorded by starting all over again with the sleeve 19 and recording the rst shave, the second shave, etc.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details-of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters lPatent is:-

1. A razor, comprising a razor head for holding a blade having indicated edges, a substantially cylindrical handle attached upon said razor head, a pair of members with inscriptions movable on said handle, a tubular member interposed between said pair of members, and means for pointing out one inscription on each of said members, said pair of members being rotatable upon the handle and upon the ends of said tubular member.

2. A razor, comprising a razor head for holding a blade having indicated edges, a substantially cylindrical handle attached upon said razor head, a pair of members with inscriptions on their opposed ends and movable on said handle, atubular member interposed between said pair of members, the ends of said tubular member engaging over and covering the inscribed portions of said pair of members, the other portions of said pair of members projecting over the ends of said tubular member to be manually engageable for selective rotation, and means for pointing out one inscription on each of saidmembers, comprising said tubular member formed with windows and normally hiding all of the indicating marks except one upon each of said members.

3. A razor, comprising a razor head for holding a blade having indicated edges, a substantially cylindrical handle attached upon said razor head, a tubular member with rotative sleeves engaged in the ends thereof and mounted upon said cylindrical handle in a manner so that the sleeves may be selectively turned, and a nut engaged upon the end of the handle for holding the tubular memberand the sleeves in place.

4. A razor, comprising a razor head for holding a blade having indicated edges, a substantially cylindrical handle attached upon said razor head, a tubular member with rotative sleeves engaged in the ends thereof and mounted upon said cylindrical handle in a manner so that the sleeves may be selectively turned, and a nut engaged upon the end of the handle for holding the tubular member and the sleeves in place, said cylindrical handle being formed with a` shoulder against which one of said sleeves bears, said nut forming an abutment for the other sleeve.
